2 D ESCRIPTION AND OPERATING PRINCIPLE
The ADV consists of a perfect y watertight, stream ined, ho ow body, see figure 1,
inside which the e ectric motor, rechargeab e batteries and speed-reduction gear are
housed. On the outside, two manoeuvring hand es (1) are found at the rear, one of
which has an integrated trigger (2) to contro prope er rotation by means of a magnetic
reed switch (3). At the front, a hand e (4) is used for gripping and carrying the vehic e.
The prope er (10) is ocated at the rear end and is protected by a surrounding circu ar
strip which constitutes the f ow conveyor (5). The main switch (6) for turning the power
on and off and the speed regu ator knob (7) are a so found at the rear.
In front is situated the head cap (8). By opening it we can access to the battery
compartment, the ocking whee (9) is inserted in the she .

After removing the she , stand the HDV vertica y, unscrew the ring nuts (11), remove
the p ate (12) (see fig. 2), the drop-trap ring (12a), unscrew and extract the ring nuts
(11a) and extract the first battery (14) pu ing it upwards off the rods (13) (see fig. 2 and
3). At the end detach the red connector (15) of the battery 14 from the battery switch
(61).
Remove the two distancers (60) from the rods (13).
Remove the switch (60) disconnecting it from the ower battery (14a).
Extract the second battery (14a).
NOTE: do not extract the second battery (14a) before the switch is
removed. Do not extract the second battery using the switch as a hand e
or hook for the battery since it cou d detach, etting the battery fa . Use
the specific hand e on the battery.
4.3 R ECHARGING THE BATTERY
To recharge the battery, extract the battery (14) from the
ADV (see fig. 4), put it in a safe p ace away from peop e
and f ammab e objects. Unscrew the charger connector
cap (24) and connect the charge connector (26) to the
battery charger (see battery charger instructions). Next
connect the battery charger power cord to the mains.
When charged, disconnect the battery charge and c ose
the connector (26) cap (24) and insert the battery in the
ADV.
Figure 4
4.4 I NSERTING THE BATTERY AND CONNECTING THE SWITCH
With the ADV in vertica position (see fig. 3), repeat the battery extraction procedure in
reverse order, being carefu to assemb e a parts in the correct order, meaning:
1. Connect the red connector (15) on the ower battery (14a) to the red engine
connector.
2. Insert the ower battery (14a) on the rod (13) unti it fu y rests on the bushings.
Make sure the wire does not interfere with the battery support. If so, remove the
battery and rearrange it.
3. Insert the two white distancers (60) (fig.
4. Insert the switch (61) matching up the re evant red and grey connectors. As soon
as it is inserted, the two green LEDs on the cover start to b ink. From this
moment on you have about one minute to connect the second battery, otherwise
the system wi not recognize it and bypass it.
5. Wait for the two eds to stay on without inserting the second battery in the ADV.
6. Insert the upper battery (14) unti it fu y rests on the distancers (60).
7. Screw-in the bushings (11a).
8. Insert the drop trap ring (12a) (fig. 2)
